A friend gave my a Dell laptop,,,I wanted to change it from Win 7 to Win 10..The install started and reported a problem with my on board Intel HD Graphics 4000 and a separate card Nvidia GT 650 M I did some on-line searches and it seems the onboard chip runs to keep the battery usage down if it isn't plugged in and If a game starts it switches to the Nvidia card I tried disabling the on board chip but the screen went black And after a reboot it showed up again..I've got windows 7 and they are dropping support for it in January,and I'd like to get it set up just for the internet and keep my main machine for gaming Any advice is appreciated
